3. And the Levites were numbered from the age of thirty years and upward. And there were found thirty-eight thousand men.
4. Of these, twenty-four thousand were chosen and distributed to the ministry of the house of the Lord. Then six thousand were overseers and judges.
5. Moreover, four thousand were porters. And the same number were the singers of psalms to the Lord, with the musical instruments which he had made for the music.
6. And David distributed them into courses according to the sons of Levi, specifically, Gershom, and Kohath, and Merari.
